pipo-sdknpm

This package is a dependency-confusion payload published at an abnormally high version (9999.0.0) targeting an internal package name (pipo-sdk). The preinstall lifecycle hook runs node callback.js || true, which collects host identity — hostname, username, platform, and current working directory — via os.hostname(), os.userInfo(), and os.platform(), and transmits that data to pbnuwvwzmktaetcsjyyjlhncsf843r5a5.oast.fun by two channels: (a) a DNS resolution of a subdomain encoding the collected fields under the OAST domain, and (b) an HTTPS POST of a JSON body containing the same fields. Any host that runs npm install — for example, an internal build system whose resolver picks the public 9999.0.0 over a legitimate internal version — will silently beacon its identity to the third-party OAST endpoint. The bug-bounty / research framing in the package metadata does not change the installer-side behavior: unsolicited host-identity exfiltration fires on install regardless of consent, and the resolver-hijack version pin ensures the payload is preferred over legitimate internal artifacts.
